assesses.

To all whom it may concern:

Be it known that I, EDWARD M. HEYLMAN, a. citizen of the United States,and a resident of South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements in Flows; andI do hereby declare the followig to be a full,

clear, and exact description of the invention,

such-aswill enable others skilled in the art to which it appertains tomake and use the same; I V

This invention relates to improvements in plows and more particularly tosuch as are equipped with power lift mechanism as illustrated in anapplication filed by me even date herewith and designated by Serial No.275,582,-oneobject of my present invention being to provide simple andefiicient means for adjusting'the plowfor depth of plowing and forleveling, independently of the power-lift means and without interferencewith the operation of latter to raise the plow to its full height.

A further objecti-s to provide adjusting devices/which shall 'act aslimiting means to control. the depth at which the plow bases shall enterthe ground, without permanent attachment to the axle of the plowstructure.

A further object is to so construct depth adjusting means for a: plowstructure having crank axles, that the same will engage the cranks inclose proximity to the wheelends of said cranks and thus preventspring-- ing or straining of the axle.

A further object is to provide adjusting means for a plow having crankaxle members for the land and furrow wheels which may be operated toadjust said axle menrbers inde pendently of each other without permanentconnection therewith.

A further object is to provide an improved construction of axlecomprising two memhere so connected that one member may be adjustedindependently of the other to facilitate the leveling of the plowstructure.

With these and otherobjects in view, the invention consists in certainnovel features of construction 1 and combinations of parts ashereinafter set forth and pointed out in the claims.

In'the accompanying drawings; Figure 1 is a plan view of a plowstructure embodying my improvements; Fig.2 is an elevation of one sideofthe structure; Fig. 3 isanz Specification of Letters Patent.

In the present instance I have shown a portion of the other plowstructure comprising two beams l-- 2 having standard portions 3-4 attheir rear ends. and to'these standards," plow bases 56 are secured. Thebeams'are suitably spaced part and connected by front and rear braces 7and 8,-said beams and braces thus forming a plowor beam frame.

Brackets 9 and spective beams, l and 2 and these brackets are formedwith toothed segments 11 and 12 respectlvely, for a purpose hereinafterexplained.

An axle 13 is mounted inhubs 14..15 on the respective brackets'9 and 10and its horizontal portion is disposed under the respective beams 1, 2so as to extend transversely thereof and from one to the other. end,-the axle 13 is provided with a crank-f arm 16 and at the free end ofthelatter, a spindle 17 is providedto receive the hub of a land *wheel18. r The other end of the axle 13 (at the furrow side of the plowstructure) enters a coupling member 19, the latter being clamped to saidaxle 13 by means of bolts 20 passing through lugs 21, and said couplingmember is' also connected with the axle 13 by means of a key 22 shown inFigs. 3 and 6; The coupling member 19 is made with a bearing 23 for thepivotal mounting of an arm 24 at one end of an axle member or crank25,"the latter being provided at its free end with a spindle 26 whichenters member 19 is formed with a flaring arm or extension 28 havingflanges 29-3O at its upper and lower edges between which the axle 10 aresecured to the re-' At one member 25 passes. It will be seen that bymeans of the coupling member 19, the two axle members 13 and 25 areconnected to-' gether in such manner that one can move relatively to theothen and that the flanged extension will serve to limit the independentmovements of the furrow-wheel axle member 25 that the upper flange 29will engage the furrow-wheel axle member 25 and force the furrow wheelback so that it will aline with the land wheel when the plow has beenraised by means of power lift mechanism segment 11. ;This-lever isprovided at its pivoted end which cooperates with the land-wheel axle'member 13', as displosed ininy copending application, and that thelower flange '30 of said coupling memberi arm will preventthe furrowwheel from kicking back thepivot of the'axle member 25 when the furrowwheel strikes a high or low place in the field.

A hand lever 31 is pivotally mountedbn with a suitable detent toengagethe toothed with; a forwardly projecting arm 32 carryingaroller'33, the latter being disposed over the-"crank 16 of axle member.13 near the forward end of said crank when theplowis innormal workingposition, said crank 16 being at that time, in an approximately.horizontal position,aas. shown in Fig. 2; A balance spring31 at one endto the lever 31 and its otherfend is connected, by ailinlsr-3l with thebracket 9 at 31c A hand :lever 3 4;fis mounted upo the bracket 10 at(Fig. 5) and;is prov1ded withla suitable'detent to engage the toothed 7segment 12, said,lev er being provided at rewwheel projects.

H 7 1 It will be observed that the hand levers 31 v and 3 L. arenot permanently connected with carried by these leversserve as stops forthe Y axle members; and by locating such stops t to) of the axle overtheaxle members near the wheeLends of the la'ter,'-the springing (abovereferred suction of the plow bases; whenf'passing through heavy spots inthe field, will be pregvented, and the changing of the adjustment ofotheplow for depth of plowing by reason ofispringing 0f axle c ranks,w i-llbe avoided.

With, the use of the jointed axle member, and -adjusting levers, the,movement of the front furrow wheel axle independently of the land wheelaxle, allows the'raisingof the front rur'row wheel OIL the frame so thatthe bottom of thejwheel will be above the "base the front/plow whenopening up, of,

To the hub 145" of the bracket?) and provided increase thedepth,the furrow wheel may be raised and the plow leveled with the landwheel and todecrease the depth, the furrow wheel may be loweredv and theplow leveled with the land wheehandwhe'n the furrow is thecorrectdepth,the, lower side of the front furrow wheel should be ona line with thebottom of the front base. 7

lVith the construction and arrangement l of adjusting levers and theparts with which they cooperate, as hereinbefore described, power-liftmechanism can be employed which can be operated to raise the plowstructure to its full height regardlessof the particular depthadjustment: at which said levers may beset.

The rearend of theend of the plow structure is supportedon arear'follower or furrow; wheel 38, the axle 39of which,;is mounted in a,bearing sleeve 40, thelatter being; 1

pivotally attached to a bracket 41 secured,

to the plow standard The'bearing sleeve .40 is provided with an arm 42normally'engaging oneend of a lever 43, which is held in adjustedposition by a screw 44. A slack v link 45 is connected with the'upperend' of 'the'turning of the axle member- 13 when the plowstructure isaraised by; the power-lift mechanism disclosed H1 mycopending appl cation. I
